Installation 🚀

Option 1: Userscript (Recommended)

1. Install Tampermonkey in Chrome
2. Copy contents of extension/yt.js and create new Tampermonkey script
3. Save and it runs automatically on YouTube

Option 2: Chrome Extension

1. Clone/download this repository
2. Go to chrome://extensions/ → Enable "Developer mode"
3. Click "Load unpacked" → Select extension folder

Usage ▶️

1. Open any editable YouTube playlist in Chrome
2. Expand the "Sort Playlist by Duration" panel injected below playlist header
3. Optional: Configure Settings, view Stats, or set duration filters
4. Select sort order: Shortest First or Longest First
5. Choose: Sort all (loads entire playlist) or Sort only loaded (current videos)
6. Recommended: Enable Dry Run to preview changes before applying
7. Click Sort and watch the real-time log
8. Optional: Export playlist data as CSV

Note: After sorting, don't switch back to YouTube's auto-sort (Date Added, etc.) - manual sorting is permanent.

Troubleshooting 🧯

• Verify Tampermonkey shows script active on youtube.com
• Reload page if controls don't appear
• Use Dry Run mode to preview before applying changes
• Adjust Settings panel for scroll retry times or log verbosity
• Use Copy Console button for detailed logs
• Check browser console for additional error messages
